The public looks forward to a brighter year after the 2020 "shock", but beyond mid-crisis hopes are still a series of challenges waiting for the world.

First, Covid-19, the cause of global turmoil in 2020, is predicted to be at greater risk.

However, vaccine delivery runs the risk of an unpredictable challenge, stemming from problems in production and logistics, delaying vaccination schedules, limiting its ability to prevent virus transmission.

Besides, movement between countries is expected to remain limited for most of 2021. Therefore, overseas distribution of vaccines, especially in developing countries, is unlikely.

Hope revived from the "ashes" of the US, the world's largest epidemic zone, is placed in President-elect Joe Biden.

According to the polls, about 70% of Republicans believe in President Donald Trump's alleged election fraud and Biden's victory is illegal, raising fears that Trump will still be a barrier.

During the "sunset" term, the Trump administration relentlessly unleashed the last "blow" on China, seemingly the last effort in separating the two countries' relations, leaving Biden without many options in

"Biden will take a multilateral approach and the pressure on China may increase but not decrease," said Yan Xuetong, professor of international relations at Tsinghua University in Beijing.

In addition to the troubled political situation, experts at the Atlantic Council also warned of another global financial crisis due to debt, stemming from the urgent, special Covid-19 bailout.

Capital flows to low-income countries are expected to decline by $ 700 billion compared to last year.

Even Western countries are expected to struggle with the slow economic recovery.

China is the only major economy forecasted to grow significantly in 2020, at nearly 2%, and possibly 10% by the end of 2021. As for the West, which is heavily influenced by the

Many economists said that the slow recovery of the US after the 2008 financial crisis was partly due to the early withdrawal of stimulus measures and the focus on reducing the deficit since 2010. Meanwhile, the policy of "tightening austerity.

Experts note that it was the 2008 financial crisis that fueled the current wave of populism in America and Europe.

The gloomy economic situation is believed to also lead to an end to the expansion of the global middle class, the world's leading achievement in the past three decades as millions have emerged from poverty.

Experts say that for the first time in half a century, the middle class has begun to shrink, estimated at 52 million people in Latin America alone.

If next year's economic growth is lower than forecast, this figure will also increase.

Another major challenge facing the world is food security.

According to UN projections, there are more people at risk of dying from malnutrition and related diseases than from Covid-19.

The World Food Program assesses possible hunger in Yemen, South Sudan, Nigeria and Burkina Faso.

However, some are still optimistic about 2021 as the "year of rise from hell", as the world seems to have been cornered in 2020 and there is no other way out but to go up.

First is the "rebirth" prospect of the World Trade Organization (WTO).

Experts say the foremost goal in 2021 is to revive the rules-based global trade, through three steps.

The reforms of multilateralism in the 21st century could facilitate the transformation of the WTO.

American leadership has the opportunity to innovate in an already reformed United Nations system, such as for solving problems in space, automated weapons, new forms of technology.

Instead of waiting for an inevitable disaster in these areas, the Biden administration can create an environment for new technologies to be used for the common good.

Politically, many international relations have a chance to improve in 2021, especially relations between Washington and Moscow.

The relationship-building process may include establishing mutual restraint, starting with an extension of the nuclear arms reduction treaty.

Relations among Middle Eastern countries are also changing positively.

Experts say the next step Washington can take to promote mediation is to facilitate a free trade and investment agreement between Sunni Muslim countries and Israel.

Covid-19, the world-devastating pandemic in 2020, is also likely to evolve in a more positive direction by 2021. Rapid vaccine development thanks to artificial intelligence, big data and cumulative research.

As predicted by health officials, by mid-2021, the world will have enough supplies of vaccines so that anyone who wants to be vaccinated can get a shot, although there will be logistical difficulties.

However, experts say changes in community behavior in 2020, including wearing masks, frequent hand washing and social exclusion, will still need to be maintained until the world is completely exited.

According to Mohamed El-Erian, president of the Global Development Council under former US President Barack Obama, the Covid-19 vaccine is not enough to induce a strong economic recovery in 2021 and maintain sustained growth after

"However, with drastic measures, inspired leadership and a little luck, policymakers can still help get the global economy on the right track," he said.
